A cigarette pack rejection device

Abstract

The control module is electrically connected to both the first and second rejection modules, and is used to send cigarette pack rejection information to both modules.

By employing the above-mentioned technical means and setting up the first and second rejection modules, a downward gas blowing force can be applied to the cigarette pack as it falls freely under its own weight, thereby rejecting the cigarette pack. This ensures thorough rejection of the cigarette pack, guarantees production efficiency, and improves product qualification rate.

Description

Technical Field

[0001] This utility model relates to the field of tobacco pack processing technology, and in particular to a tobacco pack rejection device. Background Technology

[0002] Small-box transparent paper packaging machines are the mainstream equipment for transparent paper packaging of cigarette packs in cigarette factories today. In order to ensure product quality, it is necessary to remove unqualified cigarette packs at the rejection station. When unqualified cigarette packs are detected, they are removed from the production line. This process usually involves high-speed rotating conveyor turntables and complex mechanical movements to ensure that unqualified products can be removed accurately without affecting the normal conveying of subsequent cigarette packs.

[0003] The existing rejection station relies on the free fall of the cigarette packs under their own weight. In the dynamic environment of a high-speed rotating conveyor turntable, incomplete rejection is prone to occur. Some incompletely rejected cigarette packs may be carried to the inlet of the automatic pack replenisher, causing blockages or tearing of the packs. These problems not only reduce the overall efficiency of the production line but also affect the quality stability of the products. Utility Model Content

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Figure 1 This is a schematic diagram of the structure of a cigarette pack rejection device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the cigarette pack rejection device includes: a first rejection module 10, a second rejection module 20, and a control module 30; the control module 30 is electrically connected to the first rejection module 10 and the second rejection module 20 respectively, and is used to send cigarette pack rejection information to the first rejection module 10 and the second rejection module 20, so as to control the first rejection module 10 to make the cigarette pack fall by electromagnet action, and control the second rejection module 20 to blow the cigarette pack down by gas blowing force.

[0041] Specifically, both the first rejection module 10 and the second rejection module 20 are used to reject unqualified cigarette packs, but their rejection methods differ. The control module 30 is electrically connected to both the first rejection module 10 and the second rejection module 20. Thus, when the location of an unqualified cigarette pack is determined, the control module 30 sends rejection information to both the first rejection module 10 and the second rejection module 20, causing both modules to activate simultaneously to reject the unqualified cigarette pack.

[0042] Specifically, the control module 30 controls the first rejection module 10 to reject defective cigarette packs using electromagnetic force. In other words, when a defective cigarette pack is detected, the action of an electromagnet assists in its rejection. For example, when the detector detects a defective cigarette pack, it sends a signal to the control module. The control module then issues a rejection message, the solid-state relay outputs a signal, the rejection electromagnet at the turret station is energized, and the movable guide rail at the bottom of the cigarette pack flips downwards. The defective cigarette pack then falls freely under gravity, thus achieving rejection.

[0043] Specifically, the control module 30 controls the second rejection module 20 to reject unqualified cigarette packs using gas blowing force. That is, when an unqualified cigarette pack is detected, the control module 30 sends a rejection message to the second rejection module 20. The second rejection module 20 then applies a downward gas blowing force to the unqualified cigarette pack, thus quickly rejecting it.

[0044] Specifically, in the technical solution of this utility model embodiment, when the control module 30 sends cigarette pack rejection information to the first rejection module 10 and the second rejection module 20, the first rejection module 10 and the second rejection module 20 operate simultaneously. The unqualified cigarette packs are simultaneously subjected to their own gravity and gas blowing force, which can accelerate the falling speed of the unqualified cigarette packs, thereby quickly rejecting the unqualified cigarette packs, improving rejection efficiency, and preventing problems such as incomplete rejection of cigarette packs, resulting in blockage or cigarette pack tearing.

[0045] In contrast, in existing technology, defective cigarette packs fall solely under their own weight, resulting in a slow descent. Furthermore, because the cigarette pack conveyor rotates continuously during the fall, some incompletely rejected packs may be carried to the automatic pack replenisher inlet, causing blockages or tearing. However, this invention applies a downward airflow force to the cigarette packs as they fall freely under their own weight, thus accelerating the descent and improving the rejection efficiency.

[0046] For example, the control module can be a programmable logic controller (PLC). PLCs have strong anti-interference capabilities and flexibility.

[0047] The cigarette pack rejection device provided in this embodiment of the utility model sends cigarette pack rejection information to the first rejection module and the second rejection module through the control module. In this way, the unqualified cigarette packs will be rejected under the action of their own gravity and the action of gas blowing force. That is, the unqualified cigarette packs are rejected by their own gravity and the action of gas blowing force. In other words, the unqualified cigarette packs are rejected by their own gravity and the action of gas blowing force. This ensures that the unqualified cigarette packs are completely rejected, which is conducive to improving production efficiency and product qualification rate.

[0048] Optional, Figure 2 This is an electrical connection diagram of a cigarette pack rejection device provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the cigarette pack rejection device also includes a photoelectric coupling module 40; the photoelectric coupling module 40 is connected to the first rejection module 10, the second rejection module 20, and the control module (…). Figure 2 Electrical connection (not shown); the control module is also used to send the cigarette pack rejection information to the first rejection module 10 and the second rejection module 20 respectively through the optocoupler module 40.

[0049] Specifically, the optocoupler module 40 features high sensitivity and strong anti-interference capability, making it suitable for high-speed dynamic environments. The input terminal of the optocoupler module 40 can be electrically connected to the control output terminal of the control module, the first output terminal of the optocoupler module 40 can be electrically connected to the first rejection module 10, and the second output terminal of the optocoupler module 40 can be electrically connected to the second rejection module 20. By setting the optocoupler module 40, electrical isolation can be achieved between the first rejection module 10 and the second rejection module 20, which helps prevent interference between them, thereby ensuring the stability and reliability of the cigarette pack rejection device.

[0050] Optional, continue to refer to Figure 2 The second rejection module 20 includes a first relay 201, a solenoid valve 202, and an air blowing unit. Figure 2 (Not shown in the image); the cigarette pack is located inside the conveyor turntable, and the air blowing unit is located on the side of the cigarette pack away from the conveyor turntable; the first relay 201 is electrically connected to the optocoupler module 40 and the solenoid valve 202 respectively; the solenoid valve 202 is electrically connected to the air blowing unit.

[0051] Specifically, the cigarette pack rejection signal output by the control module is transmitted to the first relay 201, solenoid valve 202, and air blowing unit via the optocoupler module 40. At this time, the first relay 201 and solenoid valve open, and the air blowing unit starts. By setting the air blowing unit on the side of the cigarette pack away from the conveyor turntable, that is, above the cigarette pack, air is blown onto the defective cigarette pack, thereby applying a downward air blowing force to the cigarette pack. In this way, the cigarette pack accelerates its fall under the action of its own gravity and the air blowing force, thus achieving the rejection of the defective cigarette pack.

[0052] For example, the solenoid valve 202 can be a high-speed solenoid valve with a response time of less than 10ms to ensure rapid action.

[0053] Optional, Figure 3 This is a three-dimensional structural diagram of a fixed bracket provided in an embodiment of the present utility model. Figure 4 for Figure 3 A top view of the corresponding fixed bracket. Figure 5 This is a three-dimensional structural diagram of an air blowing unit provided in an embodiment of the present invention. Figure 6 for Figure 5 A top view of the corresponding air blowing unit, see reference. Figures 2-6 As shown, the second rejection module 20 further includes: a fixed bracket 203; the fixed bracket 203 includes a fixed plate 2031, a fixed rod 2032, and a fixed opening 2033; the fixed rod 2032 connects the fixed plate 2031 and the fixed opening 2033; the extending direction of the fixed rod 2032 intersects the plane of the fixed plate 2031; the air blowing unit 204 includes an air pipe ( Figure 5 (Not shown in the image) Hollow tube 2041, connecting part 2042, and blowing nozzle 2043; the air pipe is connected to the air inlet end of the hollow tube 2041, the connecting part 2042 is connected to the air outlet end of the hollow tube 2041 and the blowing nozzle 2043; the solenoid valve 202 is installed in the pipeline between the air pipe and the hollow tube 2041; the blowing unit 204 is fixed on the fixed bracket 203 through the fixing port 2033.

[0054] Specifically, the fixed bracket 203 is used to fix the blowing unit 204 to ensure the stability of the blowing unit 204 during operation and to prevent the blowing unit 204 from moving due to the large blowing force, which would affect the rejection of the cigarette pack.

[0055] Specifically, the fixing rod 2032 connects the fixing plate 2031 and the fixing port 2033. The extension direction of the fixing rod 2032 intersects the plane where the fixing plate 2031 is located. For example, the extension direction of the fixing rod 2032 is perpendicular to the plane where the fixing plate 2031 is located, which is beneficial for fixing the air blowing unit 204.

[0056] Specifically, the upper end of the hollow tube 2041 can be connected to the air pipe via a quick connector, so that the gas in the air pipe passes sequentially through the hollow tube 2041, the connecting part 2042, and the blowing nozzle 2043 to blow air into the tobacco pack. A solenoid valve 202 is installed in the pipeline between the air pipe and the hollow tube 2041. Thus, when the solenoid valve 202 is open, the gas in the air pipe can flow to the hollow tube 2041; when the solenoid valve 202 is closed, the gas in the air pipe cannot pass through the hollow tube 2041. The operating state of the blowing unit 204 can be controlled by the solenoid valve 202; that is, when the solenoid valve 202 is open, the blowing unit 204 starts; when the solenoid valve 202 is closed, the blowing unit 204 shuts down.

[0057] Specifically, the air blowing unit 204 is fixed to the fixed bracket 203 through the fixing port 2033. The air blowing unit 204 can be inserted into the fixing port 2033 with the air nozzle 2043 facing downwards. The outer diameter of the connecting part 2042 is the same as the inner diameter of the fixing port 2033. In this way, the air blowing unit 204 is fixed by contacting the fixing port 2033 through the connecting part 2043, which helps to ensure the stability of the air blowing unit and prevents the air blowing unit from moving due to large gas impact force.

[0058] Specifically, the hollow tube 2041, the connecting part 2042, and the blowing nozzle 2043 are all hollow structures, which ensures that the gas in the air tube passes through the hollow tube 2041, the connecting part 2042, and the blowing nozzle 2043 in sequence to reach the tobacco pack, thereby achieving the removal of the tobacco pack.

[0059] For example, the inner diameter of the mouthpiece can be 2mm, which ensures that the airflow is concentrated and the gas force acting on the tobacco pack is moderate.

[0060] For example, the outer thread diameter of the hollow tube can be 8mm, and a 6mm quick connector can be installed on the inner thread of the hollow tube.

[0061] Optionally, the second rejection module further includes: a gas flow detection unit; the gas flow detection unit is located at the air nozzle and is used to detect the gas flow at the air nozzle; the control module is also electrically connected to the gas flow detection unit and the solenoid valve respectively, and is used to adjust the opening of the solenoid valve according to the gas flow at the air nozzle.

[0062] Specifically, the force of the gas blowing onto the cigarette pack is related to the gas flow rate at the nozzle. The greater the gas flow rate, the greater the force of the gas blowing onto the cigarette pack; the smaller the gas flow rate, the smaller the force of the gas blowing onto the cigarette pack.

[0063] Specifically, a gas flow detection unit is located at the nozzle, allowing for real-time monitoring of the gas flow at that location. The control module is electrically connected to both the gas flow detection unit and the solenoid valve. This allows the control module to adjust the solenoid valve opening based on the gas flow at the nozzle. In other words, when the gas flow detection unit detects a flow rate less than a preset value, the control module increases the solenoid valve opening to increase the gas flow rate, thereby increasing the blowing force on the tobacco pack and accelerating its descent. Conversely, when the gas flow detection unit detects a flow rate greater than the preset value, the control module decreases the solenoid valve opening to reduce the gas flow rate, thus reducing the blowing force on the tobacco pack and preventing gas waste.

[0064] Specifically, the preset flow rate can be set according to the magnitude of the gas blowing force acting on the cigarette pack. This embodiment of the utility model does not specifically limit the value of the preset flow rate.

[0065] Optional, continue to refer to Figures 3-6 The fixing port 2033 includes: a fixing nut 20331; the outer surface of the connecting part 2042 includes a first thread; the inner surface of the fixing nut 20331 includes a second thread; the first thread and the second thread are matched.

[0066] Specifically, the connecting part 2042 is fixed to the fixing nut 20331 by the first thread on its outer surface and the second thread on its inner surface. This fixes the connecting part 2042 to the fixing nut 20331, further ensuring the stability of the air blowing unit 204.

[0067] Optional, continue to refer to Figure 3 The fixing plate 2031 includes: a plurality of fixing holes 20311; along the thickness direction of the fixing plate (e.g., ... Figure 3 (As shown in the X direction), the fixing hole 2031 penetrates the fixing plate 2031; and the fixing hole 20311 is located in the edge region of the fixing plate 2031.

[0068] Specifically, the fixing holes 20311 can be distributed around the perimeter of the fixing plate. In this way, the fixing bracket can be fixed in the appropriate position of the cigarette pack rejection device through the fixing holes 20311 to ensure that the air nozzle is aligned with the cigarette pack rejection position. On the other hand, it can ensure that the fixing plate 2031 is subjected to uniform force around its perimeter, thereby ensuring the stability of the fixing bracket 203.

[0069] Optional, continue to refer to Figure 2 The first rejection module 10 includes a second relay 101 and an electromagnet 102; the second relay 101 is electrically connected to the optocoupler module 40 and the electromagnet 102 respectively.

[0070] Specifically, the cigarette pack rejection signal output by the control module is transmitted to the second relay 101 through the optocoupler module 40. At this time, the second relay 101 is turned on, the electromagnet is energized and actuates, and the movable guide rail at the bottom of the cigarette pack flips downward. In this way, the unqualified cigarette pack falls freely under the action of gravity, thereby achieving rejection.

[0071] For example, the first relay may be a first fixed relay, and the second relay may be a second solid-state relay.

[0072] Optional, continue to refer to Figure 2The first rejection module 10 also includes a first capacitor C1 and a first resistor R1; the first end of the first capacitor C1 is electrically connected to the first end of the electromagnet 102 and the output end of the second relay 101 respectively; the second end of the first capacitor C1 is electrically connected to the first end of the first resistor R1; the second end of the first resistor R1 is electrically connected to the second end of the electromagnet 102 and the grounding end respectively.

[0073] Specifically, the first capacitor C1 and the first resistor R1 connected in series can form a simple low-pass filter to filter out high-frequency noise and interference signals, improve the performance of the first rejection module 10, and thus improve the stability and reliability of the rejection device.

[0074] Optional, continue to refer to Figure 2 The second rejection module 20 also includes a second capacitor C2 and a second resistor R2; the first end of the second capacitor C2 is electrically connected to the first end of the solenoid valve 202 and the output end of the first relay 201 respectively; the second end of the second capacitor C2 is electrically connected to the first end of the second resistor R2; the second end of the second resistor R2 is electrically connected to the second end of the solenoid valve 202 and the grounding end respectively.

[0075] Specifically, the second capacitor C2 and the second resistor R2 connected in series can form a simple low-pass filter to filter out high-frequency noise and interference signals, improve the performance of the second rejection module 20, and thus improve the stability and reliability of the rejection device.

[0076] In summary, the cigarette pack rejection device provided in this embodiment of the invention, through electrical connection between the control module and the first rejection module and the second rejection module, enables defective cigarette packs to be rejected under their own weight and the force of the gas blowing. This ensures that defective cigarette packs are thoroughly rejected, which is beneficial for improving production efficiency and product qualification rate. Furthermore, it prevents blockages caused by incomplete cigarette pack rejection, thus avoiding equipment downtime.
